Specification forming part of Letters Patent No. 132,978, dated November 12, 1872.

To all whom it may concern:

Beit known that I, JAMES POOL, of Newark, Essex county, State of New Jersey, have invented a new and Improved Kaleidoscope; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable Others skilled in the art to make and use the saine, reference being had to the accompanying drawing forming part of this specification.

This invention relates to improvements in haleidoscoj'ies; and consists in the combination with the same, whether having' two or more reiiectors, ot' two lenses, under an arrangement whereby the images of external objects may be caused to take the place of the objects usually employed and be viewed in their stead.

Figure l represents a longitudinal section of a kaleidoscope arranged according to my improvement, and Fig. 2 represents a transverse section of the same taken on the line x a" of Fig. l.

Similar lettersfof reference indicate correspondin g parts.

A represents the tube ot an ordinary kaleidoscope, and B the reflectors thereof, to

which I apply in front of the said reflectors,

and preferably in a tube, O, having a telescopic connection with the tube A, an Object-lens, D,

the lens E maybe used or not, but the images are amplied by it.

Having thus described my invention, what I claim as new, and desire to secure by Let ters Patent, is-

The combination, with the ordinary tube A and reflectors B, of tube O and Objectflens I) and movable lens E, all constructed and arranged as and for the purpose specified.
